Metoprolol tart 25mg myl generic -why does pill have a line on one side & other side has M over 18?

They are just identifying markers for the manufacturer. They dont always have to do with dosage. My MSIR (morphine sulfate immediate release) 15mg tabs say 54 over 733 on the tab so it is just an identifying mark for the particular tab and may only mean something to the manufacturer.
